This Koyo steel stud-type track roller bearing with a hexagonal hole and lip seals handles moderate radial and shock loads in cam- and track-type applications. This track roller bearing, also called a cam follower, has a thick-walled outer ring that helps minimize deformation under heavy radial and shock loads. It has a non-separable, threaded stud-type design for through-hole or threaded mounting, and a hexagonal hole on the flange end that provides greater holding power during mounting than a screwdriver slot. This track roller is made of bearing steel treated with black oxide for corrosion protection, and holds a full complement of needle rollers for a higher radial load-carrying capacity than caged rollers. Lip seals on both sides of the bearing retain grease applied at manufacture and help protect against contaminants, and internal thrust washers made of self-lubricating resin help reduce sliding friction. Its operating temperatures range from -30 to +110 degrees C. Depending on size, inch series track rollers with a hexagonal socket can be lubricated through the threaded end of the stud using a standard nominal inch drive-type grease lubrication fitting, through a cross-drilled hole in the shank, or through the hexagonal socket on the stud head. (Sizes 8 to 10.1 inches cannot be relubricated.) All stud-type track rollers come with lubrication fitting plugs for closing off unused holes. This track roller bearing meets American National Standards Institute/American Bearing Manufacturers Association (ANSI/ABMA) standard 18.2 for quality assurance and is suitable for use in a broad range of applications including process transfer lines, ram support rollers, conveyors, machine tools, and indexing equipment, among others.
Sizes 8 10.1 No grease hole Size 12 and larger Relubrication through the threaded end of the stud and a cross-drilled hole in the stud shank. Sizes 12 22 Relubrication through both stud ends and through a cross-drilled hole in the stud shank. Sizes 48 64 Relubrication through both stud ends and a cross-drilled hole in the stud shank. Lubrication fittings for the axial hole in the stud head hex slot are included with the track roller.
Track runner bearings, also called track roller bearings, are rolling element bearings with a thick-walled outer ring that rotates directly on cam and track surfaces. The thick outer ring helps minimize deformation under load stress and enables the bearing to handle heavy rolling and shock loads. Track runner bearings have either a stud-type or yoke-type mounting design. Stud-type track rollers, such as cam followers, have a built-in threaded rod, instead of an inner ring, for either threaded mounting or through-hole mounting onto machine components. Through-hole mounting uses a hexagonal nut on the threaded end to secure the bearing into place. Yoke-type track rollers, such as roller followers, are mounted in a yoke-style housing on a press-fitted or push-fitted shaft or pin. Available in a variety of materials and mounting configurations, track runner bearings are used in a broad range of cam-controlled and linear motion applications including agricultural machinery, conveying equipment, cam drives, material handling equipment, robotics, and automotive equipment, among others.
